protected SparkNode()

Properties

CollectionIndex

Gets the index of this node in its owning typed collection.

Declaration
public int CollectionIndex { get; }
Property Value
System.Int32

Index

Gets the index of this node in its parent SparkElement nodes collection.

public bool IsArrangeValid { get; }
Property Value
System.Boolean

IsTreeLoaded

Gets a value indicating whether the logical tree this node is part of is loaded.

Declaration
public virtual bool IsTreeLoaded { get; }
Property Value
System.Boolean

Remarks

This actually checks for a valid SparkAreaModel reference and asks whether the area itself is loaded. This value may differ from the current NodeState.

Declaration
public RadRect LayoutSlot { get; }
Property Value
RadRect

NodeState

Gets the current state of the node.

Declaration
public NodeState NodeState { get; }

Parameters
RadRect rect

System.Boolean shouldRoundLayout

Returns
RadRect
